PATCH: Fix key ungrab handling wrt leave-notify

["Daniel P. Berrange" <dan berrange com>]

For inexplicable reasons, the event handlers I added for enter/leave-notify
to make it ungrab the keyboard are skipping events which don't have a mode
of GDK_CROSSING_NORMAL.  This is a problem, because if the mouse is grabbed
and we're in relative-mode, then when the mouse ungrab happens, you get a
crossing mode of GDK_CROSSING_UNGRAB if the host pointer is outside the
window upon ungrab.  The result is that we have the keyboard still grabbed
even though the window no longer contains the pointer. The patch simply
removes the bogus checks.
